What is cmEthernetAccPortStatsESC?
This counter tracks the number of Ethernet collision events detected on a cable modem access port in the Access-to-Network (A2N) direction. Collisions indicate that multiple devices attempted to transmit simultaneously, suggesting half-duplex operation or network congestion. An operator would monitor this metric to diagnose physical layer problems, verify port duplex mode is set correctly, or identify cable modem connectivity issues.
